Sometimes in the course of being a system administrator it is
useful to know what file systems are being mounted and when and what
mounts fail and why. While you can turn on automounter verbose
mode that only answers the question for the automounter.

and we have the answer. Who ever is calling mount assumes the file
system is read-write but fails to try read-only when the mount fails.
Flicking the switch on the side of the pen drive to read-write,
something I was going to need anyway and reinserting it and I was
away. Working out before dtrace would have been horrible this was
so quick to do that it did not interfere with my breakfast.

Now I have to file the bug.

1The
file was my first attempt at recording a presentation using
http://www.screencast-o-matic.com/
from which I learned a number of things. First while I can talk to a
room full of engineers or even a telephone without needing or
wanting any form of script and not stutter or trip over my words
when faced with a microphone that is recording I seem to have a
problem. Secondly good though screencast-o-matic is it still took me
over and hour to record 15 minutes of content and even that content
is so bad I'm not putting it on the web. Clearly something I need to
work on.
